FLAME-REGULATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 223,678, dated January20, 1880.

Application filed June 24, 1879.

To all whom it may concern:

Be it known that I, FRANZ KOESEWITZ, of Hamburg, Germ any, have inventeda new and useful Improvement in Flame-RegulatingDevices, of which thefollowing is a specification.

The object of my invention is to provide a regulating contrivance bymeans of which the flame of a burner for liquid hydrocarbon is regulatedin an easy and handy way, and which provides a perfect security againstexplosion and evaporation, as all parts containing the volatile oil arealmost hermetically closed.

In the accompanying drawings, in which similar letters of referenceindicate like parts, Figures I and III show the general View of theflame-regulating contrivance carried on in two different ways. Figs. IIandIV are the respective sections.

Referring to Fig. II, the tube cl is screwed tight into the nut c, whichis fastened hermetically to the oil-basin 0b. This tube is provided atits top with inside thread, in which the tube 1), carrying the handwheel h, is guided by corresponding thread, allowing the tube b to bemoved up and down. In Fig. IV

the tube (1 is omitted, and the tube b is directly guided in the threadof the nut 0, fastened to the oil-basin a.

The tube 1), carrying at its top the burner 6, contains the valve f,which has its seat either at the edge of the tube 1), Fig. II, or in theburner c, Fig. IV. This valve is attached to a rod, 9, whichis fastenedin Fig. II to the cross-piece s of tube 01, and in Fig. IV to astandard, 8, in the oil-basin.

The operation of the apparatus is as follows: The tube 11, made of verythin metal, after being heated, effects the evaporation of the volatileoil, such as benzoin, turpentine, &-c., whichis sucked up fromtheoil-basin by means of a wick wrapped round the rod g. The bydrocarbongases, produced in barely fifteen seconds by the eifect ofheat, pass through the In a flame-regulating device, the combination ofthe nut 0, tube b, with hand wheel h,

rod g, and valve f, substantially in the manner and for the purposeherein described.
